After using Mootools for a while, I was once more comparing it to Jquery, and was pretty lost trying to find out how to do date parsing and number formatting with the latter.<p>A search returns loads of plugins with no documentation, you don't know which one satisfies your requirements <i>and</i> is mantained.<p>In Mootools, its intuitive to find those at <a href="http://mootools.net/docs/more/Types/Date" rel="nofollow">http://mootools.net/docs/more/Types/Date</a> and <a href="http://mootools.net/docs/more/Types/Number.Format" rel="nofollow">http://mootools.net/docs/more/Types/Number.Format</a>, and you know they are good to use because they are official.<p>What is the usual approach Jquery developers take when they need something like this?
